Robotically-enhanced surgical anatomy enables surgeons to perform distal gastrectomy for gastric cancer using electric cautery devices alone
Surgical Endoscopy, 2014Co-Authors: Hirokazu Noshiro, Osamu Ikeda, Masako UrataAbstract:Background Despite recent advances in robotic urological surgery, the feasibility and clinical merit of robotic gastric surgery have not yet been fully documented. Therefore, we designed a prospective, non-randomized study to determine the feasibility and safety of robot-assisted distal gastrectomy (RADG) for gastric cancer using electric cautery devices, which are more familiar to open surgery. Methods Between April 2010 and December 2012, 181 patients treated by distal gastrectomy for gastric carcinoma were eligible for this study. According to their intent to undergo uninsured robotic surgery, 21 patients were treated with RADG (RADG group) while 160 patients were treated by conventional laparoscopic distal gastrectomy (LDG group). Under a basic working hypothesis that the superior visualization and unique movement of the robotic arms during dissection would be closely associated with reduced amount of blood loss, even though an equivalent extension of lymph node dissection was carried out, we prospectively collected data from patients in the RADG and LDG groups. Results All patients were successfully treated without conversion except for one patient in the RADG group who underwent conversion to laparoscopic total gastrectomy. In comparison with the patient groups, the estimated blood loss in patients in the RADG group treated with electric cautery devices only was smaller, but not significantly, than patients in the LDG group treated with ultrasonic-activated devices, although the same extent of lymph node dissection was achieved. In contrast, there were four patients (2.5 %) in the LDG group who developed a Pancreas Fistula or intra-abdominal abscess, while no patients treated with RADG developed such complications. Conclusions RADG using electric cautery instruments without ultrasonic-activated devices is feasible and safe. The robot enables particular surgical views, called robotically-enhanced surgical anatomy, and may contribute to reducing blood loss despite the fact that only electric cautery was used.

does fibrin glue prevent biliary and pancreatic Fistula after surgical resection
Hepato-gastroenterology, 2012Co-Authors: Atsushi Nanashima, Syuuichi Tobinaga, Masaki Kunizaki, Takashi Nonaka, Hiroaki Takeshita, Shigekazu Hidaka, Terumitsu Sawai, Takeshi NagayasuAbstract:Background/Aims: Efficacy of fibrin glue to prevent biliary or Pancreas Fistula at the resected edge of the liver or Pancreas is controversial. We examined surgical results of fibrin glue use in patients who underwent hepatectomy or pancreatectomy to assess the efficacy of its use. Methodology: Subjects were divided into two groups; the fibrin glue group in hepatectomy (n=228) and in pancreatectomy (n=113), and the non-fibrin glue group in hepatectomy (n=94) and in pancreatectomy (n=24). In case of hepatectomy, the fibrin glue was sprayed on the cut-surface or anastomotic site of hepatico-jejunostomy. In case of pancreatectomy, the fibrin glue was sprayed on the anastomotic site of pancreato-jejunostomy or closed pancreatic stump. Results: In the hepatectomy group, uncontrolled ascites were more frequent in the fibrin glue group (p<0.05). The use of fibrin glue for both groups has been less frequent in recent years. Prevalence of biliary Fistula was not significantly different between groups. Hospital stay in the fibrin glue group was significantly longer than that in the non-fibrin glue group, and was not significantly different between hepatectomy or pancreatectomy groups. There was no significant difference of any complications including pancreatic Fistula between groups. Prevalence of pancreatic Fistula was not significantly different between the fibrin glue group and the non-fibrin glue group. Conclusions: Use of fibrin glue did not prevent biliary or pancreatic Fistula in patients who underwent hepatectomy and pancreatectomy with or without enteric anastomosis.
